We prefer supported or known file formats.
- Supported formats: Public, open formats that can be used in the future through migration or emulation (e.g., .pdf, .html, .xml, .latex)
- Known formats: Proprietary but so widely used that they will almost certainly be usable for the foreseeable future (e.g., .docx, .xlsx, .psd, .mov)
- Unsupported formats: Filetypes that we can't commit to keeping usable (e.g., .wps, .exe). You can still submit them, but should provide a ReadMe file explaining how to open them, and should not expect them to be preserved forever.
To keep our system secure, any executable software files should be submitted in a .zip archive.
